There are several services like this. If Corporate Angels aren't in your
area-look around for others. My daughter, Stephanie, and I used a service like
this from Michigan to NY for a 2nd opinion at Memorial Sloan-Kettering.

You can also get financial assistance from The Sarcoma Alliance to help with
out-of-pocket expenses resulting from a second opinion. They gave us over $1000
to cover our expenses-it really helped. You just have to fill out a form.
